i may have some lobang to give u all in the ccfl light come with inverter and sound module, just pm me for detail, btw, i tried my ccfl used everyday to install in my car, fine after 5 hour running. and i off it after 5 hour, the rest i dunno, since the light can tahan 5 hour, i think it can still tahan until it reach it's lifespan about 3000hour? check on website later. the current from car is 12-14v, so maybe we need to modify a power supply unit to make sure it only pass 12v to ccfl, will update it later. and i think the unit only cost a few buck, happy diy
